JOHN PEARSON, OF CHICAGO, ILLINOIS.

CAR-ROOF.

To all whom it may concern Be it known that I, J our: PEARSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Roofs, of which the following is a specification, reference being had therein to the accompanying drawmg.

My invention relates to metallic car roofs and particularly to means for ventilating the interior of the car. When cars having metallic roofs are closed for some hours the condensation of the moisture gathers on the inner face of the roof and the water dripping therefrom frequently damages the contents of the car.

The object of my invention is to provide means for the free circulation of outside air under the metal roof to prevent this condensation.

In the drawings Figure 1 is a detail view in cross-section through the side and roof of a car on the line 11 of Fig. 3; Fig. 2 is a similar view on the line 22 of Fig. 3; Fig. 3 is a top plan view partly broken away showing one of the metal roof sheets and certain other parts shown in Fig. 1 with the offset portion of the fascia omitted, and Fig. 4 is a view similar to Fig. 1 with the fascia omitted.

In the drawings the reference letter A designates one of the side plates extending the length of the car, B one of the metallic roof sheets with its body extending from the side plate to the ridge-pole and having upstanding fian es 6 at its edges for the connecting caps %not shown). The ends of the plates at the sides of the car are bent downwardly to provide side skirts B which overlie the side fasciee C, and the skirts are pro vided with air passages in any suitable manner. As shown in the drawings the sheets are deformed or bent to provide depressions or recesses B preferably at spaced intervals where their edges overlap and the bolts D connecting them to the side plates pass through them, these recesses or depresslons extending across the width or depth of the skirt and more or less into the upper portion or body of the sheet with which they merge. The depressed portions of the skirts rest against the fascia or car side as the case may be, and the portions of the skirts intermediate these recesses stand or are spaced away from the car body to provide air chan- Specification of Letters Patent.

nels or passages E which extend into the body of the slieet to afford circulation of air between the interior and exterior of the car. a

The fasciae are spaced away from the car side by blocks or washers F arranged at intervals between them and the car body, preferably at the bolts D as shown, whereby air passages G are provided between the fascia and car side intermediate the washers, to provide circulation of air between the interior and exterior of the car. The fasciee have their upper ends bent or offset inwardly as at C toward the interior of the car to deflect the air entering through the passages G toward the center of the roof. It is obvious that by using suitable means to space the skirts away from the car body the fascia may be omitted without affecting the passages G, and that the spacing devices may be omitted when these latter passages are not required.

The arrangement of the side fasoiae spaced from the car wall provides ventilating passages between the wall and fasciae, and the employment of fasciae offset or inwardly directed at their upper ends as shown provides air deflecting passages which direct the outside air toward the center of the roof to prevent the condensation of moisture over any portion of the inner face of the roof. The arrangement of the side fasciae spaced from the car wall, and of the transversely channeled roof-sheets spaced from the fasciae provide double passages below the sheets for ventilating the car.

I claim 1. In a device of the class described, a car body having sides, metallic roof sheets having downturned skirts at their ends overlying the car side, the skirts and body of the sheets having depressions at their edges to bear uponthe car sides to space their central portions from the car body and provide air passages below the sheets into the car, and means to secure the sheets to the car.

2. In a device of the class described, a car body having sides, metallic roof sheets having downturned skirts at their ends overlying the car side, the sheets having depressions at their edges extending across the width of the skirts and into the body of the sheets to space their central portions from the car body to provide air passages into the car below the sheets, and means to secure the sheets to the car.

3. In a device of the class described, a car body having sides, metallic roof sheets having downturned skirts at their ends overlying the car side, fasciae intermediate the sides and skirts, means to space the fascia: from the sides to provide air passages below the sheets into the car, bends in the sheets to space their skirts and bodies from the fasciae to provide air passages below the sheets into the car, and means to secure the sheets and fasciae to the car.

4. In a device of the class described, a car body having sides, metallic roof sheets having downturned skirts at their ends overlying the car side, fasciae between the JOHN PEARSON. Witnesses J. McRoBER'rs, E. WILcoX.
